EARTHSS 3 Lecture 17: Lecture 17
Document Summary
Our coasts and shores: be able to describe and explain factors that control our coastline. How much sediment is supplied and what type of sediment. Sediment provided by rivers or wave erosion and transport along coast. Tides affect how high and low the waves are acting get different areas exposed to waves. Waves are main way that material is eroded, transported, and deposited. Human activity: be able to identify whether a coastline is mainly erosional or depositional from the presence of various landforms e. g. sea arches. Deltas form where rivers deposit more sediment at the coast than can be transported away offshore or by longshore currents.
